Charlotte, North Carolina (CNN) — It’s 10 p.m. in Charlotte’s trendy NoDa district, and a handful of women and one man have hunkered down over French press coffee and caramel pastries that are so amazing the cafe’s owners were once invited to the White House.

These customers have gathered at Amelie’s, a 24-hour French bakery, with a serious mission. They want to end human trafficking.

As volunteers for Compassion to Act, a faith-based nonprofit, they meet regularly to discuss how to rescue and restore the lives of human trafficking victims. But with the Democratic National Convention gathered just down the road this week, they and other groups have stepped up their efforts.
